Why leading developers love Rasa

Rasa Stack offers a truly AI-based conversation flow with full control. It's the only production ready platform delivering flexible and natural conversations that scale.

- Founder of Mr. Bot (developed the bot for Yellow Pages)

Rasa Stack gives us back control over our NLU. It’s been easy to train and customize to our use cases. We can use Rasa directly from our Python code, without network overhead, meaning we can save 200ms on user requests.

- Eyal Yavor, CTO of Meekan

If you're serious about conversational software you can't rely on 3rd party APIs. Our use case is extremely demanding and Rasa handles it well.
